Questions & Answers
What size are these ZENITH cup head bolts?
Each bolt is M8 with a 40mm length, supplied with matching nuts in a 25 pack.
How thick is hot dipped galvanising?
Hot dip galvanising leaves a thicker zinc coating than standard plating, giving stronger corrosion resistance outdoors.
What does the square neck do?
It beds into timber so the bolt does not spin while you tighten the nut.
What can I fasten with these?
They suit fastening timber to timber, metal to timber or metal to metal.
Are nuts included?
Yes, a matching hex nut is supplied for every bolt.
